You have to work with those sessions that are in
the current group.  Rather, you are looking at
all sessions and getting the total sum.

Use:

  <xsl:value-of
select="format-number(sum(current-group()/Notes/@hours-worked),'.00')"/>

You've already correctly created the groups, you
just aren't using them having created them.

BTW, the <xsl:for-each select="."> is meaningless
and does nothing except render your context list
to be only a single item which is not
useful.  Although you don't need the set of
groups in your solution, not having that
<xsl:for-each> would give you more information
about the current group within the set of groups.

I hope this helps.
